HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

Power Control
If active, the manageability firmware is responsible for monitoring the power switch on the front
panel. Setting this switch to the ON position is a signal to the MP to turn on 48 V DC power to
the server. The PE command can also be used to send this signal. This signal does not always
generate a transition to the powered state. The following conditions prevent the manageability
firmware from applying 48 V DC power to the server:
• Insufficient number of active bulk power supplies
• Insufficient number of I/O fans
• Insufficient number of main fans
• Ambient temperature is in an OVERTEMP HIGH condition
Unless one of the following conditions occurs, 48 V DC power to the server is maintained:
• A main fan failure causes there to be an insufficient number of main fans.
• A I/O fan failure causes there to be an insufficient number of I/O fans.
• Ambient temperature reaches an OVERTEMP HIGH condition.
• The front panel power switch is turned OFF.
• The PE command is issued to the manageability firmware to turn off power to the server
cabinet.
Firmware Updating
The server MP pulls a firmware update from an FTP server over the management LAN.
Instructions
• The user logs in to the server console through the LAN, local serial, or remote serial locations.
• The user types the FW command to start the firmware update.
NOTE: The LAN configuration for the server must be set for the FTP connection to function correctly
regardless of whether the console LAN, local serial, or other connection is used to issue the FW
command.
FW – Firmware Update
• Access Level: Administrator
• Scope: Complex
• Description: This command prompts the user for the location of the firmware software and the
FLASH handle (from a list) which represents all upgradeable entities.
DFW – Duplicate Firmware
• Access Level: Administrator
• Scope: Complex
• Description: This command allows field support personnel to copy firmware already installed
on the system to an equivalent entity in the same complex.
Figure 60 illustrates the output and questions requiring responses. After the user replies Y to the
confirmation request, the firmware update makes the connection to the FTP server at the IP address
given using the user and password details supplied. The appropriate files will be downloaded and
burned into the selected flash memories. Note that the firmware update validates the image to
determine that the image name supplied is that of a valid image type before burning the image
into the flash memory.
